Relative Detectability: Extremely difficult to detect due to nocturnal habits and infrequent hooting. Breeding is somewhat easier to confirm in eastern Oregon, where the species frequently nests in abandoned magpie nests.

Challenge: Determine extent of breeding in the Cascades and in western Oregon. This is among the least-understood species that nest in Oregon.
